Description

Technical Field

[0001] The present disclosure relates to tobacco machinery, and in particular to a material transportation system and a packaging production system. Background Art

[0002] Large-scale industrial production systems usually include multiple workstations, where raw materials need to be processed in different processes to eventually become products for sale. The workstations are generally connected by conveyor belts, where raw materials are placed on the conveyor belts one by one and moved from one workstation to the next.

[0003] For example, in a tobacco production system, when the wrapping line of a packaging machine needs a stack of trademark paper, the conveyor belt will carry the stack of trademark paper placed on it and move it toward the packaging machine until it reaches a designated position so that the packaging machine can proceed to the next process. At the same time, the next stack of trademark paper is also placed on the conveyor belt. However, in actual production, there is a certain gap between the stack of trademark paper placed on the conveyor belt after continuous belt running and the previous stack of trademark paper, and this gap limits the number of stacks of trademark paper placed on the conveyor belt, thereby affecting the overall production volume and production efficiency. In addition, during the start-up and transportation of the conveyor belt, the stack of trademark paper is prone to tilt or even fall over, causing the equipment of the next process to be unable to operate the stack of trademark paper normally, requiring manual correction of the stack of trademark paper, and sometimes even causing downtime, affecting the work efficiency of the production line.

[0029] In the following description, the first direction A corresponds to Figure 1 The so-called "front end" refers to the Figure 1 The right end of the material on the moving part; "end" refers to the Figure 1 The left end of the material on the moving part.

[0030] The present disclosure provides a material transport system, including a conveyor 3, a gripping device 5 and a detection device. The conveyor 3 includes a moving part that reciprocates along a first direction A, and the moving part is configured to transport a material 11 from a first transport position to a second transport position along the first direction A. The moving part can be, for example, Figure 1 The conveyor belt 31 is shown. The first transport position can be located at Figure 1 The second transport position can be the inner side of the left edge of the conveyor belt 31 shown; Figure 1The inner side of the right edge of the conveyor belt 31 is, for example, a position aligned with the second detection portion 7 on the conveyor belt 31 in a direction perpendicular to the first direction A. In an embodiment not shown, the moving portion may also be a conveyor plate chain, a conveyor roller, a trolley with pulleys, and the like.

[0031] The gripping device 5 includes a holding portion and a driving portion, and the holding portion is drivingly connected to the driving portion. The holding portion is configured to hold the material 11 to be transported, and the holding portion may include, for example, a clamping claw, a fork, etc. The driving portion is configured to transport the material 11 held by the holding portion from the storage position to the first transport position. The storage position may be, for example, Figure 1 The material 11 is shown in its position on the material storage plate 2 .

[0032] The detection device includes a first detection unit 8, and the first detection unit 8 is configured to detect first position information that the end of the material 11 located on the moving part has reached the third transport position. The third transport position is located between the first transport position and the second transport position and is close to the first transport position. By reasonably setting the interval between the third transport position and the first transport position, the end of the material 11 located at the third transport position can be in contact with the material 11 located at the first transport position or the gap between them is very small.

[0033] The first detection unit 8 may include, for example, a photoelectric detector (e.g., a photoelectric switch, a photoelectric sensor, etc.), a laser sensor, a proximity switch, etc. For example, the use of a laser sensor is conducive to reducing the requirements for spatial light, and detection can be performed even under production conditions with weak ambient light. For example, when the lighting equipment in the workshop is damaged, the laser sensor can still maintain the detection function, which is conducive to maintaining the normal operation of the material transportation system.

[0034] The detection device is coupled with the moving part and the gripping device 5 , the moving part is configured to stop moving according to the first position information, and the holding part is configured to release the held material 11 to the first transport position according to the first position information.

[0035] The holding part and driving part of the gripping device are arranged to transport the material 11 to the moving part located on the conveying platform, and the first detection part of the detection device detects the first position information that the end of the material 11 reaches the third transportation position, so that the moving part stops moving according to the detection result of the detection device, and the holding part releases the material 11 to the first transportation position according to the detection result of the detection device, and the material 11 is then moved from the first transportation position to the second transportation position through the moving part. This arrangement utilizes the interval between the third transportation position and the first transportation position, so that the material 11 released by the holding part fits with the end of the material 11 located at the third transportation position or there is a small gap. It is beneficial to arrange the material 11 closely on the moving part, so as to prevent the material 11 from tipping over during transportation to delay the production progress. In addition, it is also beneficial to improve the space utilization rate of the moving part, improve the operation efficiency, and thus increase the production volume.

[0036] In some embodiments, the first detection portion 8 includes a first photodetector, a first laser sensor, or a first proximity switch installed on the conveying table 3 in a direction perpendicular to the first direction A and located outside the third transport position.

[0037] The first detection unit 8 is provided to include a first photoelectric detector, which is beneficial to improving the detection accuracy. In addition, the first photoelectric detector occupies a small space, which is beneficial to a compact space structure. The first photoelectric detector is arranged outside the third transport position along the first direction A, which is beneficial to shortening the distance between the first photoelectric detector and the material 11 to be detected, thereby helping to reduce interference in signal transmission and improve the accuracy of detection. This centralized layout also facilitates the maintenance and management of various equipment in the material transportation system. The first detection unit 8 is provided to include a first laser sensor or a first proximity switch, which is beneficial to improving the working efficiency of the first detection unit 8 in a weak light environment.

[0038] In some embodiments, the detection device includes a second detection unit 7. The second detection unit 7 is configured to detect second position information that the front end of the material 11 on the moving part has reached the second transport position, and the moving part is configured to stop moving according to the second position information.

[0039] The second detection unit 7 is set to detect the second position information, and the moving unit stops moving according to the second position information, which is convenient for the next process of the production line and is beneficial for automatically positioning the material 11 at the next working position, so as to improve the automation level of the production line, reduce manual intervention, and reduce costs and increase efficiency.

[0040] In some embodiments, the second detection unit 7 includes a second photodetector, a second laser sensor, or a second proximity switch installed on the conveying table 3 in a direction perpendicular to the first direction A and located outside the second transport position.

[0041] The second detection unit 7 is provided to include a second photoelectric detector, which is beneficial to improving the detection accuracy. In addition, the second photoelectric detector occupies a small space, which is beneficial to a compact space structure. The second photoelectric detector is arranged outside the second transport position along the first direction A, which is beneficial to shortening the distance between the second photoelectric detector and the material 11, thereby helping to reduce interference in signal transmission and improve the accuracy of detection. This centralized layout is also convenient for maintenance and management of various equipment in the material transportation system. The second detection unit 7 is provided to include a second laser sensor or a second proximity switch, which is beneficial to improving the working efficiency of the second detection unit 7 in a weak light environment.

[0042] In some embodiments, the gripping device 5 is coupled to the moving part and configured to output a discharge signal. The moving part is configured to move the material 11 on the moving part from the second transport position to the first transport position according to the discharge signal until the moving part stops moving according to the first position information.

[0043] This setting is conducive to coordinating the moving direction of the moving part. Before the material 11 to be transported is placed on the moving part, the moving part first moves the material 11 placed on the moving part toward the direction close to the material 11 to be transported, which is conducive to shortening the gap between the materials 11, improving the stability of the transportation of the materials 11, and avoiding the dumping of the materials 11 to affect the next process. This setting is also conducive to reducing manual operations, thereby reducing the pause and processing time of human intervention during the transportation of the materials 11. In addition, the setting of the moving part and the grasping device 5 to cooperate in operation is conducive to improving the degree of automation of the material transportation system, improving the accuracy and stability of the operation, and thus improving production efficiency.

[0044] In some embodiments, the material transport system further comprises a packaging machine. The packaging machine is located at one end of the conveying platform 3 away from the first transport position (not shown). The packaging machine is coupled to the moving part and is configured to output a material request signal. The moving part is configured to move the material 11 on the moving part toward the packaging machine according to the material request signal.

[0045] The material transport system includes a packaging machine, and the packaging machine and the moving part are arranged to work in cooperation, which is conducive to coordinating the moving direction of the moving part so that the material 11 automatically moves to the packaging machine through the moving part, which is conducive to reducing manual intervention in the production process, thereby improving the degree of automation and production efficiency of the material transport system.

[0046] In some embodiments, the gripping device 5 is coupled to the packaging machine, and the driving unit is configured to drive the holding unit to move the held material 11 from the storage position to above the first transport position according to the material request signal and then stop until the holding unit releases the material 11 to the first transport position according to the first position information.

[0047] The grabbing device 5 is arranged to cooperate with the packaging machine, and the driving part is arranged to drive the holding part to hold the material 11 and move it according to the material request signal, and the holding part releases the material 11 according to the first position information, which is conducive to realizing the automatic supply of the material 11, so as to maintain the continuous operation of the packaging machine and maintain the balance of feeding and requesting of the material transportation system. This arrangement is also conducive to reducing human intervention in the operation process to improve production efficiency.

[0048] In some embodiments, the gripping device 5 is coupled to the moving part and configured to output a discharge signal, and the moving part is configured to move the material 11 located on the moving part from the second transport position side to the first transport position side according to the discharge signal. The moving part is configured to move along the first direction A toward the direction close to the packaging machine according to the discharge signal when the packaging machine and the gripping device 5 simultaneously output the material request signal and the discharge signal.

[0049] This arrangement is conducive to overall coordination of the moving direction of the moving part. When the packaging machine and the gripping device 5 release the material request signal and the material release signal at the same time, this arrangement is conducive to maintaining the normal operation of the moving part, so that the moving part moves directly in the direction close to the packaging machine according to the material request signal, that is, it gives priority to maintaining the operation continuity of the packaging machine, which is conducive to increasing production.

[0050] In some embodiments, the material transport system further comprises a controller 9 . The detection device is coupled with the moving part and the gripping device 5 via the controller 9 .

[0051] In some embodiments, the controller 9 described above can be implemented as a general processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components or any appropriate combination thereof for performing the functions described in the present disclosure.

[0052] This arrangement is conducive to centralized control of the material transportation system, maintaining stable operation of the material transportation system, and is conducive to increasing the operating modes of the moving part and the gripping device 5 according to different work requirements, thereby achieving flexible control of the material transportation system.

[0053] In some embodiments, the moving part includes a conveyor belt 31, and the gripping device 5 includes a multi-axis robot. For example, the driving part of the gripping device 5 can be set as a robot arm.

[0054] The embodiment of the present disclosure also provides a packaging production system, including the above-mentioned material transportation system. The material 11 of the packaging production system is a stack of label paper stacked into a cube.

[0055] Combine the following Figure 1 and Figure 2 The material transportation system and transportation principle of the embodiment of the present disclosure are described in detail.

[0056] The material transportation system includes a material storage plate 2, a conveying platform 3, a gripping device 5, a packaging machine, a controller 9 and a detection device. The material storage plate 2 is located at the front side of the conveying platform 3, and the plurality of materials 11 stacked on the material storage plate 2, that is, the materials 11 on the material storage plate 2, are located at the material storage position. The moving part of the conveying platform 3 is set as a conveyor belt 31 extending in the left-right direction. The working position of the packaging machine is set at a position close to the right end of the conveyor belt 31 (not shown). The gripping device 5 includes a holding part and a driving part, and the driving part drives the holding part to hold the material 11 located at the material storage position to the first transportation position located inside the left end edge of the conveyor belt 31. The detection device is configured to detect the first position information and the second position information of the material 11 located on the conveyor belt 31. The detection device detects the first position information, indicating that the end of the material 11 on the conveyor belt 31 moves to the left to the third transportation position through the moving part. The detection device detects the second position information, indicating that the front end of the material 11 on the conveyor belt 31 moves to the right to the second transportation position through the moving part.

[0057] The detection device includes a first photodetector and a second photodetector. The first photodetector is installed on the outer side of the conveying platform 3 in a direction perpendicular to the first direction A, and is aligned with the third transport position in the left-right direction to detect whether the end of the material 11 has reached the third transport position. The third transport position is set on the right side of the first transport position, and the material 11 located at the third transport position is close to the material 11 located at the first transport position. This setting is conducive to preventing the two adjacent materials 11 on the conveyor belt 31 from tipping over during transportation, and making the layout of the materials 11 on the entire conveyor belt 31 compact. The second photodetector is located on the same side of the conveying platform 3 as the first photodetector, and is aligned with the second transport position in the left-right direction to detect whether the front end of the material 11 has reached the second transport position. The second transport position is arranged in coordination with the working position of the packaging machine, so that when the moving part stops according to the second position information, the packaging machine is provided with the material 11 to be packaged. The detection device and the gripping device 5 are respectively located on both sides of the conveying platform 3, so that the gripping device 5 has enough movement space to avoid mutual interference between the gripping device 5 and the detection device during movement.

[0058] The controller 9 is respectively connected to the first photodetector and the second photodetector of the detection device, the moving part, the packaging machine and the gripping device 5 by signals, thereby achieving coupling of the detection device, the gripping device 5, the moving part and the packaging machine.

[0059] The holding portion includes a connecting plate 511, two first clamping jaws 512 and two second clamping jaws 513. The connecting plate 511 is a square plate (in an embodiment not shown, the connecting plate 511 can be any other shape), the first clamping jaw 512 is arranged below the connecting plate 511 and is perpendicular to the connecting plate 511, and has a first holding element 121 at one end away from the connecting plate 511. The two first clamping jaws 512 are arranged at intervals along the same side of the connecting plate 511. The two first holding elements 121 are arranged opposite to each other and are configured to hold the upper part of the material 11. The second clamping jaw 513 includes a rod with a square cross-section, which is rotatably connected to the bottom of the connecting plate 511, and the maximum rotation angle is 90°. The second clamping jaw 513 has a second holding element 131 at one end away from the connecting plate 511, and the second holding element 131 is a triangle with right-angled sides, and one of the right-angled sides of the triangle is connected to the rod of the second clamping jaw 513. On the side parallel to the side of the connecting plate 511 where the two first clamping jaws 512 are located, the two second clamping jaws 513 are arranged at intervals, and the second holding elements 131 of the two second clamping jaws 513 are arranged opposite to each other. The second holding element 131 is configured to hold the lower part of the opposite surface of the material 11 when the rod of the second clamping jaw 513 is perpendicular to the connecting plate 511, and gradually release the lower part of the opposite surface of the material 11 when the rod of the second clamping jaw 513 rotates in the direction close to the connecting plate 511. The detection device is coupled to the holding part through the controller 9, so that the second clamping jaw 513 of the holding part rotates relative to the connecting plate 511, thereby holding or releasing the material 11.

[0060] The driving part includes a base 54, a turntable 53 and a mechanical arm connected by a first connecting rod 521, a second connecting rod 522 and a third connecting rod 523. The base 54 and the material storage plate 2 are located on the same side of the conveying platform 3. The turntable 53 is arranged on the base 54 and is rotatable around the vertical direction, and its maximum rotation angle is 360°. The end of the first connecting rod 521 of the mechanical arm away from the second connecting rod 522 is connected to the turntable 53, and the end of the third connecting rod 523 away from the second connecting rod 522 is connected to the connecting plate 511. The controller 9 is connected to the turntable 53 and the mechanical arm signal of the driving part respectively, so as to drive the mechanical arm to change the working position by rotating the turntable 53, and the mechanical arm is moved to drive the holding part to move. The mechanical arm drives the holding part to move to the top of the material storage plate 2 or the conveyor belt 31, so that the holding part moves the material 11 held by it from the storage position to the first transportation position.

[0061] The packaging production system of the embodiment of the present disclosure includes the above-mentioned material transportation system, and the material 11 is a stack of trademark papers stacked into a cube.

[0062] The following describes in detail the transportation principle of the packaging production system including the material transportation system, taking the material 11 as a label paper stack as an example.

[0063] When the packaging machine sends out a material request signal, the controller 9 controls the conveyor belt 31 to move rightward according to the material request signal. When the second photoelectric detector detects that the front end of the trademark paper stack is located at the second transport position and sends out the second position information, the controller 9 controls the conveyor belt 31 to stop moving according to the second position information. The packaging machine operates the trademark paper stack that has reached the second transport position. At the same time, the controller 9 transmits a signal to the drive unit and the drive unit drives the holding unit to move a trademark paper stack from its storage position to above the first transport position from the storage plate 2.

[0064] When the holding part sends out a discharge signal, the controller 9 controls the conveyor belt 31 to move to the left according to the discharge signal. When the first photoelectric detector detects that the end of the trademark paper stack is located at the third transport position and sends out the first position information, the controller 9 controls the conveyor belt 31 to stop moving according to the first position information. Subsequently, the controller 9 controls the holding part to move according to the first position information, so that the second clamping claw 31 rotates in the direction close to the connecting plate 511 to release the trademark paper stack to the first transport position, so that the trademark paper stack located at the first transport position and the trademark paper stack located at the third transport position are close to each other.

[0065] When the controller 9 receives the material discharge signal and the material request signal at the same time, the controller 9 moves the conveyor belt 31 to the right according to the material request signal until the second photoelectric detector detects the second position information, and the controller 9 controls the conveyor belt 31 to stop moving according to the second position information.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present disclosure can still be modified or some technical features can be replaced by equivalents, which should all be included in the scope of the technical solution for protection requested by the present disclosure.
